Nine's

There are several of ways to help students recall facts using 9 as a product.  You can show them the trick with the hands of putting down the finger of the other factor of nine and then reading the product as the remaining combination of fingers.  You can have them think of multiplying by 9 as multiplying by 10 and subtraction 9. 

But, if student's are on pace in the leveled program, they are only learning 5 new facts, four of which are turn-around facts. 

Another great way for students to explore their 9's is have them make a list of the complete number sentences for the facts in order and ask them to look for patterns.

I have included a short video for multiplying by 9.  This is meant to be more of a review and practice instead of a concept introduction.

Spinner Tool

Students are given one of the spinners to fill out as a reference tool.  The tool will be primarily used during the current level of the multiplication program but should be kept as a reference going forward to higher levels. 

Flashcards

There is a set of flashcards provided for the current level.  Each set of flashcards include the facts with their turn-around facts.  It is important that the students are comfortable with the commutative property of multiplication.  

Games for Practice

Jumbo Tic-Tac-Toe

• Each player chooses one factor (2-12)
• Record the factor in the top of second column
• Toss 2 dice and find the sum
• Multiply the sum by the factor
• Record the product next to the sum in the table
• If the sum has already been filled, lose a turn
• First player to complete the table wins

Line It Up

• Toss 2 dice and find the sum
• Multiply the sum by 2
• Place a counter on the product
• If the product has a counter on it, lose a turn
• First player to build a full row or column wins

Face-Off

• Each player chooses one factor (2-12)
• Record the factor in the top of second column
• Toss 2 dice and find the sum
• Multiply the sum by the factor
• Record the product next to the sum in the table
• If the sum has already been filled, lose a turn
• First player to complete the table wins

There are two timed tests associated with this new factor.  The first timed test is designed to be a one minute test of 40 problems and includes only multiplication facts with the new factor.  The second timed test is designed to be a two minute test of 60 problems and includes all multiplication facts learned in the leveled program thus far.
